Our coop is painted on the inside (though only one coat) as is the ladder down into the run. The ladder and area right inside the pop door has areas of poop on it that I can't get off. The chickens don't mind it, but it grosses me out. I scrape it almost daily when I do the poop boards under the roosts, but there are still areas that are sort of dried on and stained. Is this just the way that chicken coops are? Is there a better way to clean it? I'm using a wire brush to try and scrub it off, but it never really gets clean. I can't decide if I'm being obsessive compulsive or if our coop is disgustingly dirty!
